EARL I'I. SHERBONDY, OF DETROIT, M'ICHIGAN, ASSIGNOR TO SIDNEY ID.TALDON, OF

DETROIT, MICHIGAN.

CONTROL MECHANISM.

To all whom it may cancer/1 Be it known that I. EARL H. SHERBONDY,

and State of Michigan. have invented cer tain new and usefulImprovements in Control Mecl'ianism, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to control mechanisms such as are used on motorvehicles for shifting the gears, applyingthe brake, etc, and theinvention consists in various features of construction as hereinafterset forth.

In the drawings:

Figure l is a longitiulinal section through the control, showing thesame as mounted on the housing of the transmission gearing;

Figure 2 is a cross-section thereof; Figures 3, l and 5 are respectivelya plan view, sectional side elevation and sectional end elevation of theslides for the gear shift; Figures 6, 7 and 8 are side elevations of thepins.

My improved control mechanism is of that type in which a universallypivoted lever is laterally adjustable when in neutral position intoalternative engagement with a plu rality of notched slides or gearshifters and is then longitudinally adjustable for the operation of theshifter with which it is engaged. 'One of thefeatures of the inventionis the construction of the slides or shifters and the manner of mountingthe same. Another feature is the means for determining the selectiveengagement of the control lever with various slides or shifters and themanner of mounting said lever to permit of readily removing andreplacing the same.

In detail, A, B and C are three slides or gear shifters arranged inparallelism and slidably mounted in hearings in the cross bars D, whichare mounted on studs E rising" from the frame of the transmissiongearing. Each of the shifters preferably formedof a plane cylindricalbar for engaging the bearings and a member F sleeved thereon having' thedepending shifter fork G and the upwardly extending notched lug H forengagement with the control lever. The members F are locked to the rodsby suitable means. such as the screws or pins I, and areaccuratelylocated by jig work. One of the cross bars D has formedthereon a series of pockets J, J and. J for the reception ofSpecification of Letters Patent.

spring-pressed plungers K for engaging notches in the rods A, B and (lto yieldably hold the same in the different positions of adjustment. Thebar D is also transversely bored at L and balls M, or equivalent meansare placed in this bore, these being of greater diameter than the spacebetween the rods and alternatively engaging notches therein to lock oneof the rods when the adjacent one is shifted from neutral. Thus all ofthe, shifters A, B and C are substantially the same in construction anddiffer only in the members F thereof.

The control lever N is mounted in the cover 0 of the transmissiongearing housing being provided with the ballll' for engaging thespherical. socket O in an upwardly-e2;- tending portion 0 of the cover:The portion of the lever N which extends within the housing is providedat its free end. with a knob P for engaging the notches in the lugs H,this knob being of a width corre sponding to the width of the lock andshift able laterally from one lug to another. To determine the positionsfor engagement with the respective lugs, the lever N is transverselybored to receive a slidable pin Q, the ends of which are rounded andabut against parallel guide plates R on opposite sides of the lever andmounted on the cover 0. The pin is provided with one or more shouldersQ, for engagement with latch dogs Q which as shown are arranged inrecesses upon opposite sides of the lever and are pressed inward bysprings Qfi secured by the bolts Q The arrangement is such that when thelever N is rocked laterally, the engagement of the dogs with theshoulders can be felt so that the operator will know when the lever isin proper registration with anyone of the slides. As shown in Figure P,the pin Q, has three notches therein for each of the three positions ofthe lever N, in Figure '2' the pin has only two notches, and Figure 8only one. In the latter case the notch or shoulder Q, is used merely fordetermining registration with the inter In assembling; the structure then he quickly iplllltiChQCl. to their n ngiedfwith the hearings in the D.These cross burs may then e with tie studs E sn of a uni 4.5 altermeansi said lecomprising; u
